bathypelagic

“It's believed to be a scavenger that feeds upon dead whales and squid in the pitch black darkness of the bathypelagic zone, some 2140m/7020ft below the water surface. giant ispods went on display at the Sea Life Centre at Blackpool for the first time in Britain last year.”

“Instead, trapped in the deep, the oil fouls the ocean's twilight and dark zones: the mesopelagic and the bathypelagic (bathos: deep).”

“Oceanographers divide the ocean into five broad zones according to how far down sunlight penetrates: the epipelagic, or sunlit, zone: the top layer of the ocean where enough sunlight penetrates for plants to carry on photosynthesis. the mesopelagic, or twilight, zone: a dim zone where some light penetrates, but not enough for plants to grow. the bathypelagic, or midnight, zone: the deep ocean layer where no light penetrates. the abyssal zone: the pitch-black bottom layer of the ocean; the water here is almost freezing and its pressure is immense. the hadal zone: the waters found in the ocean's deepest trenches.”

“Oceans  Shallow ocean waters (euphotic zone) contain a greater concentration of organisms than the rest of the sea  Phytoplankton (algae) is food not only for zooplankton (protozoans and microscopic animals) but also for small fishes  Coral reefs - areas of biological abundance just below the surface in shallow, warm, tropical waters  Chief constituents are stony corals, animals that have a calcium carbonate (limestone) exoskeleton, and calcareous red and green algae  Most of the ocean lies within the pelagic zone  Epipelagic zone lacks the inorganic nutrients of shallow waters, and therefore it does not have as high a concentration of phytoplankton  Animals in the deeper waters of the mesopelagic zone are carnivores, which are adapted to the absence of light,  Waters of the bathypelagic zone are in complete darkness except for an occasional flash of bioluminescent light  Abyssal plain - many invertebrates survive there by feeding on debris floating down from the mesopelagic zone”
